egress from the cooking area, a minimum of 10 feet and a maximum of 20 feet from
the kitchen exhaust system. The manual activation device shall be located a minimum
of 4 '/z feet and a maximum of 5 feet above the finished floor. Instructions for
operating the fire suppression system shall be posted adjacent to manual activation
device. 509.4 OMSC

Appliance Protection
The following pages detail types of appliance protection. Each
design requires several factors; correct nozzle choice, correct noz-
zle height above hazard, correct pozzle location and correct aim-
ing point.
Fryer — Single Nozzle Protection
1. Design requirements for fryers are broken down into two •
types.
A. FRYERS WITHOUT DRIPBOARDS
If the fryer does not include a dripboard, measure the
internal depth (horizontal dimension from front to back)
and length of the frypot.
B. FRYERS WITH DRIPBOARDS
If the fryer includes any dripboard areas, measure both
the internal depth (horizontal dimension from front to
back) and length of the frypot portion, and then measure
the internal depth and length of the overall hazard area
including any dripboard areas.
2. Using Table, 'Maximum Cooking Area Dimension — Single
Nozzle Fryer Protection," determine which nozzle is needed
to protect the fryer based on the maximum dimensions listed.
A. If the fryer does not include a dripboard, use the maxi-
mum dimensions listed in the first column of the table to
select the correct nozzle.
B. If the fryer includes any dripboard areas, use both the
maximum frypot dimensions in the first column of the
table, and the maximum overall dimensions in the second
)‘--)
column of the table to select the correct nozzle. None of
the maximum dimensions in either column may be
exceeded.
3. If either the maximum frypot or the overall sizes are exceed-
ed, an additional nozzle(s) will be required. Refer to the mul- �+ , Q
tiple nozzle requirements.
E A fryer with a dripboard. The inside of the frypot without
14k
the dripboard measures 18 in. in depth x 18 in. in length (46 cm x
46 cm) and the inside of the overall area including the dripboard
measures 18 in. in depth x 24 in. in length (46 cm x 61 cm). From U
the Table 'Maximum Cooking Area Dimension — Single Nozzle \k
Fryer Protection," either the 3N or the 290 nozzle should be select-
ed to protect the fryer, depending on the maximum nozzle height
above the fryer and the positioning requirements allowed. Refer to
appropriate Figures.
